Lead is already banned in petrol in many countries in Europe. Now, older petrol engines with valve seats which require leaded petrol for lubrication are threatened with: ˜ higher valve-seat wear ˜ noticeable loss in compression, i. e. lower engine performance ˜ or even engine damage. Lead Substitute facilitates lead-free operation of passenger motor vehicles. Lubricates and protects non-hardened valve seats against wear. Therefore protects against engine damage. For optimum compression.
